Asbestosis vs Mesothelioma

Asbestos is a group of minerals found in nature and used in construction and insulation. It can harm health if breathed in, causing two main problems: asbestosis and mesothelioma.

Asbestosis and mesothelioma are both linked to asbestos, but they are different in how they affect the body, their symptoms, and what might happen in the future. This article explains these differences to help you know more about them and how to spot them early. 


Asbestosis vs. Mesothelioma

Asbestos, a mineral group found naturally and often used in construction and insulation, is harmful to health.
Breathing in asbestos fibers can cause two conditions: asbestosis and mesothelioma.
While both come from asbestos exposure, they are different in how they affect the body and their symptoms. This article explores asbestosis and mesothelioma, giving you information to help prevent and detect them early.


Asbestos and Its Impact: Asbestosis vs Mesothelioma

Asbestos fibers are microscopic, fire-resistant, and were once considered a wonder material. However, these very properties make them dangerous when inhaled. The body struggles to remove these fibers, leading to chronic inflammation and scarring.

What is Asbestosis?: Asbestosis vs Mesothelioma

Asbestosis is a non-cancerous lung disease. Inhaled asbestos fibers lodge deep in the lungs, causing irritation and scarring of the lung tissue. Over time, this scarring thickens and stiffens the lungs, making it increasingly difficult to breathe.

Symptoms of Asbestosis:

  • Shortness of breath, especially during exertion
  • A persistent dry cough
  • Chest tightness or pain
  • Fatigue
  • Crackling sounds in the lungs (wheezing)
  • Fingernails that curve inwards (clubbing) – in later stages

Diagnosis of Asbestosis:Asbestosis vs Mesothelioma

Diagnosing asbestosis often involves a combination of:

  • Medical history: A doctor will inquire about potential asbestos exposure.
  • Physical examination: Checking for breathing difficulties and clubbing.
  • Chest X-ray: To identify scarring in the lungs.
  • Pulmonary function tests (PFTs): To assess lung function and capacity.
  • High-resolution CT scan: May provide a more detailed view of lung scarring.

Treatment of Asbestosis: Asbestosis vs Mesothelioma

Asbestosis doesn’t have a cure. Treatment aims to ease symptoms and improve life quality. It may involve:

  1. Oxygen therapy: Providing extra oxygen in severe cases.
  2. Bronchodilators: Medicines that relax airways for easier breathing.
  3. Pulmonary rehabilitation: Exercises to strengthen breathing muscles and lungs. In rare cases, a lung transplant might be an option.

Does Asbestosis Mutate?: Asbestosis vs Mesothelioma

No, asbestosis itself is not a form of cancer and doesn’t involve mutations. However, it can significantly increase the risk of developing lung cancer.


Mesothelioma, unlike asbestosis, is a rare and aggressive form of cancer. It develops in the mesothelium, the thin layer of tissue lining various organs, including the lungs, abdomen, and heart.
Asbestos fibers trapped in the mesothelium can damage the DNA of these cells, leading to uncontrolled growth and tumor formation.

Symptoms of Mesothelioma: Asbestosis vs Mesothelioma

  • Shortness of breath
  • Chest pain, often worsening with coughing or deep breathing
  • Persistent cough
  • Fatigue
  • Weight loss
  • Night sweats
  • Fluid buildup in the abdomen (peritoneal mesothelioma)
  • Difficulty swallowing (pleural mesothelioma)

Diagnosis of Mesothelioma: Asbestosis vs Mesothelioma

Diagnosing mesothelioma can be challenging due to its similarities with other conditions. It often involves:

  • Medical history: Similar to asbestosis, a doctor will inquire about potential asbestos exposure.
  • Physical examination: Checking for breathing difficulties and fluid buildup.
  • Imaging tests: Chest X-ray, CT scan, or MRI scan to visualize potential tumors.
  • Biopsy: Removal of a tissue sample for microscopic examination to confirm cancer.

Treatment of Mesothelioma: Asbestosis vs Mesothelioma

Treatment options for mesothelioma depend on the stage and location of the cancer. It may involve a combination of:

  • Surgery: To remove as much of the tumor as possible.
  • Chemotherapy: Medications to kill cancer cells.
  • Radiation therapy: Uses high-energy rays to destroy cancer cells.
  • Immunotherapy: Helps the body’s immune system fight cancer cells.

Does Mesothelioma Mutate?

Yes, mesothelioma is a cancer caused by mutations in the DNA of mesothelial cells. Asbestos exposure damages these cells, leading to uncontrolled growth and tumor formation.

Prevention is Key: Asbestosis vs Mesothelioma

The best defense against both asbestosis and mesothelioma is to prevent asbestos exposure in the first place. Here’s how:

  • If you work in a setting where asbestos might be present (construction, demolition, renovation), wear appropriate protective gear and follow safety protocols.
  • If you suspect asbestos in your home (older buildings often contain asbestos), avoid disturbing it. Consult a professional for asbestos abatement (removal).
  • Be aware of asbestos-containing products like old insulation materials and take precautions if encountering them.
